What is PayPal +1(855) 852-0124 Add Cash at Stores and how do I use it?

Here’s how to add cash in the PayPal app:

Tap PayPal balance from the Home tab or the Accounts tab.
Tap Add Cash at Stores on the PayPal balance page.
Select a retailer to generate a barcode. Wait until you’re at the retail location to generate the barcode on your phone. Once you get the barcode on your mobile phone, it’ll expire after 1 hour. If it expires, you’ll need to create a new one.
Present the barcode on your smartphone to the cashier at your selected retail store and give the cashier the amount of cash you want to add.
The cashier will scan your barcode and add the money to your PayPal Balance account.
The cashier will give you a receipt and the money will be added to your balance within 15 minutes.
If you have a PayPal-branded Debit Card, you can use it to add cash to your PayPal Balance account without generating a barcode. Provide the cash you want to add at the register and swipe your card or hand it to the cashier to swipe.
